Can agarose gel electrophoresis be used for proteins?
Agarose gel is utilized for the electrophoretic matrix, and detection of proteins is accomplished by transfer of the proteins to a membrane that is probed with specific antibodies and chemiluminescence reagents. Alternatively the protein can be detected in the gel using radiolabeled antibodies and autoradiography.
What is serum protein electrophoresis?
Description. Serum protein electrophoresis (SPEP) is an easy, inexpensive method of separating proteins based on their net charge, size, and shape. The 2 major types of protein present in the serum are albumin and the globulin proteins.
Can we separate proteins by gel electrophoresis?
Gel electrophoresis is a laboratory method used to separate mixtures of DNA, RNA, or proteins according to molecular size. In gel electrophoresis, the molecules to be separated are pushed by an electrical field through a gel that contains small pores.
What is the difference between agarose gel electrophoresis and SDS-PAGE?
The main difference between gel electrophoresis and SDS PAGE is that gel electrophoresis is a technique used to separate DNA, RNA, and proteins whereas SDS PAGE is a type of gel electrophoresis used mainly to separate proteins.
What does serum protein indicate?
A total serum protein test measures the total amount of protein in the blood. It also measures the amounts of two major groups of proteins in the blood: albumin and globulin.
What diseases does a serum protein electrophoresis test for?
This lab test measures the types of protein in the fluid (serum) part of a blood sample. This fluid is called serum….Increased alpha-1 globulin proteins may be due to:
- Acute inflammatory disease.
- Cancer.
- Chronic inflammatory disease (for example, rheumatoid arthritis, SLE)
What is the difference between SDS-PAGE and agarose gel electrophoresis?
The main difference between gel electrophoresis and SDS PAGE is that gel electrophoresis is a technique used to separate DNA, RNA, and proteins whereas SDS PAGE is a type of gel electrophoresis used mainly to separate proteins. Generally, SDS PAGE gives a better resolution than the regular gel electrophoresis.
What are the bands separated in serum protein electrophoresis?
Electrophoresis fractions Serum protein electrophoresis separates serum proteins into the following fractions: albumin, alpha, beta and gamma globulins. Approximately 60% of the total protein in the serum is albumin, while the remaining fractions are composed mainly of globulins, predominantly immunoglobulins.
What is the purpose of protein electrophoresis?
Protein electrophoresis is a test that measures specific proteins in the blood. The test separates proteins in the blood based on their electrical charge. The protein electrophoresis test is often used to find abnormal substances called M proteins.
How does gel electrophoresis work for proteins?
With electrophoresis, proteins travel through a gel matrix, inside a small box, which is usually used in scientific labs. An electric current pushes the proteins through the gel. The current acts like a little helper in each lane, shoving the proteins to their equilibrium state, where they won’t move anymore.
What is agarose used for in gel electrophoresis?
Agarose gel electrophoresis has proven to be an efficient and effective way of separating nucleic acids. Agarose’s high gel strength allows for the handling of low percentage gels for the separation of large DNA fragments.
What is the main difference between protein electrophoresis and DNA electrophoresis?
As the name implies protein electrophoresis is used to determine proteins in a sample and DNA electrophoresis is used to determine DNA segments (and later sequences) in a given sample.
How is protein gel electrophoresis different from DNA gel electrophoresis?
Why is serum protein test important?
A total protein test measures the amount of protein in your blood. Proteins are important for the health and growth of the body’s cells and tissues. The test can help diagnose a number of health conditions, including: kidney disease.
Why did my doctor order serum protein electrophoresis?
Your doctor will usually order a UPEP test if they suspect that you have a condition that causes elevated protein levels in urine, such as multiple myeloma or amyloidosis. Your doctor may also order this test if an earlier test showed there was protein in your urine.
Why is agarose gel used in electrophoresis?
Why is SDS used in protein electrophoresis?
SDS-PAGE separates proteins primarily by mass because the ionic detergent SDS denatures and binds to proteins to make them uniformly negatively charged. Thus, when a current is applied, all SDS-bound proteins in a sample will migrate through the gel toward the positively charged electrode.
What tube is used for SPEP?

What is the principle of agarose gel?
Principle of Agarose Gel Electrophoresis DNA is visualized by including in the gel an intercalating dye, ethidium bromide. DNA fragments take up the dye as they migrate through the gel. Illumination with ultraviolet light causes the intercalated dye to fluoresce. The larger fragments fluoresce more intensely.
How do SDS-PAGE and agarose electrophoresis gels differ?
